Khardung La and the Drive to Nubra Valley

North of Leh, the road climbs fast. Within a few kilometres of the city the landscape strips itself bare — no trees, no fields, just bare mountain and a road that keeps going up. Khardung La sits above 5,300 metres and is the principal pass connecting Leh to the Nubra Valley beyond. Crossing it is not a sightseeing detour. It is the only road in, and it is part of what makes Nubra feel genuinely remote rather than merely scenic.

The drive takes most of a day when you factor in the pass, the descent, and the check posts. What you find on the other side — a warmer, lower, greener valley with sand dunes and a river system and views back toward the Karakoram — is dramatically different from the landscape around Leh. Knowing what the road involves makes the difference between a smooth trip and a stressful one.

Khardung La: What the Pass Is

Khardung La (also written Khardung-La or Kardung La) is a high mountain pass in the Ladakh Range, north of Leh. The pass has been widely claimed as one of the highest motorable roads in the world — a claim that has been contested by altitude measurements that put the actual summit somewhat below the signboards suggest. The realistic figure is somewhere around 5,300–5,360 metres; the exact elevation depends on measurement method and which point on the road you measure. What is not in dispute: it is very high, and you feel it.

The pass is managed by the Border Roads Organisation (BRO), which maintains it as a strategic military supply route to the Siachen sector and beyond. It is generally open from May through November, with winter closures when snowfall makes the road impassable. In peak season — July and August — it is the busiest high pass in Ladakh, with a steady flow of tourist vehicles, military trucks, and motorcyclists.

The summit area has a chai shop, toilets, and the BRO signboards that make it one of the most photographed spots in Ladakh. It is cold at the top even in midsummer — wind chill on an exposed summit above 5,000m is not to be underestimated regardless of the season. A jacket that was in your bag in Leh needs to be accessible before you reach the top.

The Road from Leh to the Summit

Leaving Leh, the road passes through the village of Khardung and begins climbing in earnest. The ascent from Leh (at roughly 3,500m) to the pass (around 5,300m) covers approximately 39km of road — which sounds short but takes considerably longer than the distance implies. The road is narrow in places, subject to one-way traffic control in the busiest sections, and steep enough that overtaking is rarely safe.

The gradient is relentless. Hairpin bends on the upper section gain altitude quickly, and the road surface varies from reasonable tarmac to broken stretches where the mountain has pushed through. BRO works on the road throughout the season, which sometimes means construction delays. Morning departure from Leh — ideally by 7 or 8am — gives you the best road conditions: less traffic, clearer visibility, and the full day ahead for the valley below.

At altitude, vehicle engines lose power. Diesel engines handle high altitude better than petrol ones; both will feel sluggish on the climb if the vehicle is not in good condition. The engine stress on a steep road at 5,000m is real — overheating is a risk if you push hard. The standard advice is to go slowly, keep the revs reasonable, and stop if the temperature gauge rises. Most modern vehicles make the crossing without incident when driven sensibly.

The Pass Summit: What to Expect

The summit of Khardung La is marked by the BRO signboard, prayer flags strung across the road, and typically a cluster of vehicles — military trucks, tourist SUVs, motorcyclists, and the occasional bicyclist who has made the ascent under their own power. The chai shop is basic but functional. The views are expansive in good weather: the Ladakh Range stretching in both directions, the Karakoram visible to the north on clear days.

The altitude at the summit is significant. If you are visiting Nubra as part of your first few days in Leh — before full acclimatization — the top of Khardung La is not a place to linger. Headache, breathlessness, and nausea are all common at over 5,000m in people who have not yet adapted. Keep the summit stop brief. Take photographs, have tea if you want it, and get moving. The descent on the north side brings you to lower altitude quickly.

Our guide to altitude acclimatization in Leh covers when to time day trips to high passes relative to your arrival date. The general principle: at least two full days of rest in Leh before attempting a pass above 5,000m.

The Descent into Nubra

The descent from Khardung La on the north side is the more dramatic half of the drive. The road drops steeply from the pass into the upper Nubra valley, and the landscape changes with the altitude. By the time you reach the valley floor — at somewhere around 3,000 metres, significantly lower than Leh — the air feels noticeably richer and the temperature warmer. Trees reappear. The Nubra River, milky with glacial sediment, runs through the valley floor.

The valley itself sits between two significant mountain systems: the Ladakh Range to the south (which you just crossed) and the Karakoram Range to the north. The Karakoram, home to K2 and several other of the world's highest peaks, is a constant presence on the northern skyline when weather permits. The scale of the Karakoram is difficult to process from the valley floor — what look like medium-sized mountains are among the tallest on Earth.

Diskit is the main town in Nubra Valley and is where most travellers base themselves. The Diskit Monastery sits above the valley on a rocky outcrop — one of the older monasteries in Ladakh — and is worth the walk up regardless of how long the drive has been. The Hunder sand dunes, a few kilometres from Diskit, are the other focal point: a small but striking area of sand dunes in a high-altitude river valley, with double-humped Bactrian camels that were historically part of the Silk Road trade routes through this region. Our guide to Nubra Valley covers the valley's highlights in full.

The Inner Line Permit

Nubra Valley requires an Inner Line Permit (ILP) — a permit granted by the district administration that allows travel to restricted border areas. Indian nationals apply for the ILP; foreign nationals require a Protected Area Permit (PAP), which has the same function but a different process. Both are obtained in Leh, not at the pass checkpoint, though there is a checkpoint at the base of the descent where permits are verified.

Arrange your permit before departure — the same day as the drive is possible if you start early, but it adds unnecessary stress. Our full Inner Line Permit guide explains the process, costs, and timing for 2026.

Practical Logistics

A few things that make the crossing smoother:

• Fuel: Fill up in Leh before departing. There is no reliable fuel on the Khardung La road; the nearest fuel in Nubra is in Diskit. With the distance to the pass and the descent, plan for a full tank out of Leh.
• Timing: Start early — 7 to 8am from Leh is standard. The pass is busiest mid-morning when day-trippers from Leh arrive. An early start gets you over the summit before peak traffic and gives you the full afternoon in the valley.
• Warm layers: Pack a proper jacket accessible in the vehicle, not in the boot. The summit is cold regardless of what the Leh morning felt like.
• Cash: Nubra Valley runs largely on cash — ATMs in Diskit are limited and unreliable. Withdraw in Leh before leaving. Our cash guide for Ladakh covers how much to carry and where to withdraw.
• Signal: Mobile coverage on Khardung La and in much of Nubra Valley is limited or absent. Download offline maps and any directions you need before leaving Leh.
• One or two nights: Nubra Valley rewards spending the night — the light on the Karakoram at sunset and the star visibility from the valley are both reasons to stay. Day trips from Leh miss the valley when it is at its best.

When to Go

Khardung La is typically open from late May through November, with the peak tourist season in July and August. July gives you clear skies, warm valley temperatures, and long days. August is similarly good. September is quieter and the light is often better for photography. October brings cold nights in the valley and the risk of early snowfall closing the pass — possible but manageable with proper planning.

Avoid attempting Khardung La before acclimatizing to Leh altitude. Going to a 5,300m pass within 24 hours of arriving in Leh at 3,500m is how altitude sickness trips begin. Two full rest days in Leh, with short walks and plenty of hydration, is the minimum preparation.
